To all whom it may concern:

Be it known that I, JOSEPH HAUK, Jr, a citizen of the United States, residing at Milwaukee, county of Milwaukee, and State of 'lVisconsin, have invented new and useful Improvements in Sterilizing Apparatus, of

which the following is a specification.

My invention-relates to improvements in apparatus for sterilizing milk, beer, and other liquid foods and beverages, and it pertains more especially, among other things, to the means employed for automatically conveying a large number of crated bottles in which the liquid is stored successively through a plurality of separate compartments, which are respectively supplied with water of successively higher and lower temperatures whereby the bottles and their contents will be gradually heated from a comparatively low to a high temperature and such contents sterilized, when the bot.- tles are thereafter conveyed through the compartments in which the water is of successively lower temperature, whereby the liability of such bottles becoming broken by a too rapid change of temperature, is reduced to the minimum.

The construction of my invention is explained by reference to the accompanying drawing:, in which Figure 1 is a plan view thereof. Fig. 2 is a vertical section of the central portion of the apparatus. Fig. 3 is an end view, part broken away to show the interior. Fig. l is a detail, showing an enlarged end viewof the driving mechanism. Fig. 5 is a side view of the driving mechanism shown in Fig. l. Fig. 6 is side view; and Fig. 7 an end view of one of the crate support ing conveyors showing the track from which the conveyers are suspended and the device for moving such crates longitudinally of said tracks.

Like parts are identified by the same reference figures troughout the several views.

1 is a water tank, which is divided into a plurality of stparate compartments 2, 3 and 4, by the transverse partitions 5 and 6 and the compartments and 4; arer'espectively divided by the central vertical par tition beneatl'i and above which the crates are carried in their annular course through the tank as more full hereinafter del n S scribed. Each of the compartments 2, 6 and 4, are provided with two annular carrying collars 8, which collars are in turn revolubly supported from the stationary collars 9 through a plurality of intermediate anti-friction rollers 10, roller supporting shafts 11 and roller supporting brackets 12, while the several bottle crates 13 of the series are con nected with and temporarily suspended from said shafts 11, through the hangers 14, whereby it will be understood that when said collars 8 are revolved, all the crates in the annular series will be successively immersed beneath the water in the tank 1 and carried from thence back to the starting point above the longitudinal center of the tank.

It will be understood that the crate carrying collars, together with the operating mechanism, are revolved with an intermittent movement which is so timed that the crate carrying hangers arestopped as each one is successively brought to each starting point above the longitudinal center of the inclosing tank when each hanger of the series is supplied with a crate until all the hangers in such annular series has been thus supplied. It will be obvious that when all the hangers in the first series have been thus supplied, the first hanger will have completed its circuit in the first compartment, when the crate in such harger is moved forward from such compartment into the hanger of the next succeeding compartment and its place supplied. with another, and this step in the process is repeated until all the crates in the first annular series have been moved forward from the first compartment into the next succeeding compartment, and the process is again and continuously repeated until all the crates have passed through all the compartments of the tank. It will be understood that all the crates in being thus conveyed through the tank, will each successively pass in an annular course through each successive compartment and that when each compartment has been thus filled with crates, they will be successively withdrawn from the last compartment of the series as they have completed their annu lar course in such series and their places will be successively supplied with fresh crates from the exterior, 'lhe first compartment 2 of the ser being provided, as stated, with a vertical partition 7 and the sections are revolubly suspended at their respective ends from the movable collars 8, through the hangers l2 and shafts 11, whera by, when the crates are moved forward from one movable track section 15 to another, they over the intermediate stationary sections 16. The position of the stationary track 16" is such that the several sections 15 are successively brought into alinement with them as they reach the vertical above the longitudinal center of the tank. The G8- neva gear is provided with a plurality of concave bearing surfaces 64,-which as the pins 56 are brought out of contact with the slots 57, are adapted to bear against the con vex surface of the flange carried by the gear 21, whereby said Geneva gear is prevented from turning, while all that part or the convex surface 65 between the points 66 and 7 are passing beneathsuch concave surface (3d, and whereby such gear is retained in such position that the driving pins 56 will freely enter said slots 57, when said gear 22 has completed its annular movement,

While the mechanism for conveying the crates of bottled goods into and from the sterilizing tank and for carrying saidcrates in a circular course through each compar ment of said tank, each comprise several cooperating parts, for brevity of description, such conveyors are respectively hereinafter referred to in the claims as horizontal and revoluble conveyors. twill be understood that the conveyer track comprising said stationary and movable sections, extends longitudinally through the several compartments of said tank and from thence around its exterior, whereby the crate carrying hangers and crates are thereby conveyed in a continuous course through and then around one side of said tank. The endless conveyor chain heretofore referred to is suspended centrally beneath said track throughout its entire length in such a manner that the brackets 4 2connected with said chain, are adapted to engage the depending fin l1 connected with said crates, whereby when said chain EHOVQCL'lllE required movement will be communicated. from said chain to said crates and said crates moved forward through the several compartments of the tank as previously described.

Having thus described my invention, What I claim as new, and desire to sec .re by l ettcrs Patent, is-

1. In apparatus of the combination a size;

, des riocd of annular stationary crate supporting collars mounted in said tank, a pair of annular revoluble collars each provided with a plurality of roller bearings surrounding and supported from said stationary collars, a plurality of sets of crate carrying hangers pivot-ally suspended from said revoluble collars, means for conveying bottle crates from the exterior of said tank into position to be carried by said hangers, means for communicating an intermittent movement to said revoluble collars, and means for moving t ie crates ?from the hangers of said tank after they have completed their annular course therein;
